Now when a gAMA chunk is set on an imported PNG (and if there is no profile attached), an equivalent profile is created out of the gAMA chunk. So the displayed image looks like it is supposed to. On export, the generated profile should simply be saved together in the PNG file. If not, the sRGB chunk is set anyway (and also an equivalent gAMA/cHRM as recommended in the specs). So basically we now have a proper support of the gAMA chunk, from import to export, and display within GIMP takes this metadata into account appropriately (in the shape of a generated equivalent profile). Therefore it looks to me keeping the option is redundant. It is even confusing (because it's actually hard to understand exactly what this data is about, even our documentation about this metadata seems to be wrong) hence possibly dangerous if someone thinks it is important, checks the box, which would override other data or simply create irrelevant or contradictory metadata. So let's just remove this option. Development releases are the right places anyway for people to notice this change and come to us if we missed some usage regarding this option. See also #5363.

GNU Image Manipulation Program
2.99 Development Branch
------------------------------
This is an unstable development release, an intermediate state on the
way to the next stable release: GIMP 3. GIMP 2.99 may or may not do what
you expect. Save your work early and often. If you want a stable
version, please use GIMP 2.10 instead.
If you think you found a bug in this version, please make sure that it
hasn't been reported earlier and that it is not just new stuff that is
still being worked on and obviously not quite finished yet.
If you want to hack on GIMP, please read the file HACKING. For
detailed installation instructions, see the file INSTALL.
1. Web Resources
================
GIMP's home page is at:
https://www.gimp.org/
Please be sure to visit this site for information, documentation,
tutorials, news, etc. All things GIMP-ish are available from there.
There you can get the latest versions of plug-ins, using a convenient
forms-based interface.
The latest version of GIMP can be found at:
https://www.gimp.org/downloads/
2. Mailing Lists
================
We have several mailing lists dedicated to GIMP user and development
discussion. There is more info at
https://www.gimp.org/mail_lists.html
Links to several archives of the mailing lists are included in that page.
Gimp-user-list is a mailing list dedicated to user problems, hints and
tips, discussion of cool effects, etc. Gimp-developer-list is oriented
to GIMP core and plug-in developers. Gimp-gui-list is for discussing
about GIMP interface to improve user experience. Most people will only
want to be subscribed to gimp-user-list. If you want to help develop
GIMP, the gimp-developer mailing list is a good starting point; if you
want to help with GUI design, the gimp-gui list is where you want to
subscribe.
3. IRC
======
And finally, for the real junkies, there is an IRC channel devoted to
GIMP. On GIMPNet (a private free software oriented network) there is
#gimp. Many of the developers hang out there. Some of the GIMPNet
servers are:
irc.gimp.org:6667
irc.us.gimp.org:6667
irc.eu.gimp.org:6667
4. Customizing
==============
The look of GIMP's interface can be customized like any other GTK+ app
by editing files in `${XDG_CONFIG_HOME}/gtk-3.0/` (settings.ini and
gtk.css in particular) or by using "themes" (ready-made customizations).
Additionally, GIMP reads `${XDG_CONFIG_HOME}/GIMP/2.99/gimp.css` so you
can have settings that only apply to GIMP.
Included is a set of keybindings similar to those in Adobe Photoshop.
You can find them in the ps-menurc file. To use them, copy this file
to `${XDG_CONFIG_HOME}/GIMP/2.99/menurc`. You can also manually change
the keybindings to any of your choice by editing:
`${XDG_CONFIG_HOME}/GIMP/2.99/menurc`.
Have fun,
